Gerald Howarth, a junior defence minister who opposed equal rights for gay couples in the armed forces and marriage equality generally says the government’s proposals to allow gay and straight couples equal access to civil marriage were a contributing factor in election losses last night.

In local elections around the UK, Labour made large gains on the Conservatives, gaining hundreds of seats and the control of 22 councils, an estimated 39 percent of the vote over the Tories’ 31 percent, according to BBC figures.

Mr Howarth, Minister for International Security Strategy, told the BBC: “There are issues, for example, like the proposals for gay marriage.

“A lot of Conservatives have written to me saying ‘I am a lifelong Conservative, there is no mandate for this, why is this being proceeded with?’.

“There is the business of trying to change the House of Lords. Do we need to do this at a time when the nation is preoccupied with restoring the public finances?”

“This is a Christian country and Christian teaching is very clear on these matters and I am extremely concerned that young people today are being bombarded with literature which suggests that a homosexual relationship is the same as a heterosexual relationship, which it is not.”

Figures also appeared to show that potential losses in Conservative voters in a general election would be substantially, though not entirely, made up by voters attracted from Labour and the Liberal Democrats by the commitment to equal marriage, which has similarly been made by those parties’ leaders.

Although extrapolated from a small sample, marriage equality appeared set to win back 10 percent of disenchanted Tory voters and reconfirm 30 percent of the group’s decision to no longer support the party.

Tim Farron, president of the Liberal Democrats, told BBC Radio 4’s Today programme that more right-wing policies at this point would be ‘bonkers’.

He said: “It was almost amazing that the Tories managed to not win the 2010 general election but the thought that they would somehow build themselves up to a majority by lurching to the right to try and bring back people they think they’ve lost to UKIP – insofar as anyone in the Tory Party should take political and strategic advice from me, can I just advise them that would be bonkers.”

Foreign Secretary William Hague said: “These results, while it is never a good feeling to lose councillors, are well within the normal range of mid-term results for governments.”

Labour MP Chris Bryant said this morning that Tories who claimed marriage equality for gay couples or Lords reform as reasons for the loss were “barking”, and that the Labour boost was down to the state of the economy.
